Designed and engineered by Traxxas, the XL-5 Electronic Speed Control handles the elements while smoothly supplying power to the motor. This high-performance ESC is packed with impressive specifications that are normally only found on more expensive high-end replacement units. The XL-5 features a completely waterproof design, three throttle profiles, Thermal Shutdown Protection, 4-7 cell compatibility, and built-in BEC. High frequency operation combined with ultra-low resistance make the XL-5 an efficient and ultra-smooth fully proportional speed control. An exclusive feature on the XL-5 is the patented Training Mode™. This profile reduces the overall power output of the XL-5 by 50% making it easier for young or new drivers to develop their control skills before unleashing full-power operation. XL-5 is equipped with two-stage low-voltage detection (LVD) to allow LiPo battery use. The XL-5 is manufactured by Traxxas to ensure the highest level of quality and support. The XL-5 is backed by the Traxxas Lifetime Electronics Warranty.
